People who say it better than I can - NEJM edition

"Admission to higher-volume hospitals was associated with a reduction in mortality
for acute myocardial infarction, heart failure, and pneumonia, although there was a
volume threshold above which an increased condition-specific hospital volume was
no longer significantly associated with reduced mortality."
The thresholds in the study were <610 cases for AMI, <500 for HF, and <210 for pneumonia.  I do not know what Alameda's case numbers are although I am pretty sure they fall below those numbers for at least one of these conditions.
